Chevy Warns Against Capacity Loss in the Bolt’s Battery

2

Those interested in buying the Chevrolet Bolt may want to read its owner’s manual first.

Currently available online through Chevrolet, the owner’s manual reveals the American automaker expected battery degradation of 10 to 40 percent during the warranty period of eight years or 100,000 miles. That means there’s a possibility that the Bolt’s range could decrease to 143 miles when the eight-year warranty period is up.

Battery capacity loss is expected with electric vehicles, or realistically any device using a rechargeable battery, but it’s worth mentioning for those considering a purchase.

The Chevrolet Bolt is rated at 238 miles, so taking 40 percent of that would be 95.2, which appears to be the worst-case scenario.

“Like all batteries, the amount of energy that the high voltage ‘propulsion’ battery can store will decrease with time and miles driven,” it says in the owner’s manual. “Depending on use, the battery may degrade as little as 10% to as much as 40% of capacity over the warranty period. If there are questions pertaining to battery capacity, a dealer service technician could determine if the vehicle is within parameters.”

Also revealed in the manual is that the Bolt EV will accept a charge rate of at least 80 kilowatts for DC fast-charging, allowing a depleted battery pack to recharge 90 miles of range in 30 minutes.

The Chevrolet Bolt should be arriving dealerships later this month, likely in California first.

    Current version of this story shows “Volt’s range could decrease to 143 miles” should read as “Bolt”.

    Calling it the Bolt was a stupid decision. It sounds too much like Volt. People are going to be mixing up the names on a regular basis.
